T all whom it may concern Be it known that. I, Knvrr'r Ro'rirnnrmanf subject of the King of Great Britaimresid- 'ing at 27 Spon street," Coventry, in the county of lVarwick, England, have invented a certain new and useful Improved Fastener or Coupler; and I do hereby declare that the followin is a full, clear, and exact descrip- 1*) tion of the same.

The invention provides an improved fastener or coupler particularly applicableto theends of bracelets,- necklets, and similar bands andlengths, and consisting of a combination of parts operating most efiiciently in securing the two loose ends to each other in an easily detachable manner, extremely heat in design, and very simple for finger operation.

' The accompanying drawings illustrate the invention in its most'desirable form applied for coupling up two end links of a metal bracelet or like band, but it will beobvious that the combination of parts maysbe read ily applied for detachably securing the two loose ends of any bandor'length, or for sew curing two lengths; I

Figure 1 is an external plan of the fas tener applied to the two end links, which are shown connected up. Fig. Qis anlunderside plan of Fig. 1. 'Fig. 3is a side elevation. of' Figflu Fig; 4- is a sectional plan of'Fig 1 Fig. 5 isa section of Fig. l on the dotted lines A B. Fig. 6 is a section. similar ,to Fig. 5 but showing how thetwo end links are detached. Fig. 7 is a section similar to Figs. 5 and 6cbut with the end links detached and separated.

The one link to be" connected up is represented by the longitudinal hollow barga n, which are; oppositely arranged a: distance apart and carry the movable partsofjthe fastener means. The other link to be con nected up is represented at 0 and is formed to nicely fit the parallel space 0 between the bars a, a, up to the intermediate link, d, against which the end 0 of the link 0 abuts longitudinally of the bracelet parts. The

pair of bars a, a form the outer link and the link 0 is the inner link and this latter has formed integral with it at e a lug or projection which depends from its under or inner side and is of the same thickness as said link 0 and adapted to fit the space 0 between the pair of bars a. This lug or projection is provided at 6 c with undercut seatings, and at e, c with inclined faces opsAsTEnEn on enemas. I

The combination of parts hereinbefore described in their formation and operation are subject to some modifications all contained within the scope of the claims.

Having now described my invention what I claim and desire to secure by Letters Patent is 1. In a fastener, the combination of a member provided with a rigid lug having opposite, under-cut seatings; and a second member provided with a space for the reception of sail lug and with a fixed bolt and a spring-controlled movable bolt extending across said space for engagement in said seatings, said members having portions thereof abutting against each other to prevent endwise movement of said members toward each other when said bolts are thus engaged.

2. In a fastener, the combination of a member provided with a rigid, longitudinal projection formed with alug having opposite, under-cut seatings and oppositely-inclined faces leading into said seatings; and a second member provided with a space for the reception of said projection and its lug, and with a fixed bolt and a spring-controlled movable bolt extending across said space for engagement with said seatings, said projection abutting at its free end against the inner end wall of said space, to prevent endwise movement of said members toward each other when said bolts are thus engaged.

3. In a fastener, the combination of a member provided with a rigid lug having opposite, under-cut seatings and oppositely inclined faces leading thereinto; a second member provided with a space for the reception of said lug and with chambers at opposite sides of such space; fixed and movable bolts mounted on the second member and extending across said space and into said chambers for engagement in said seatings; and springs arranged in said chambers and bearing against the movable bolt to hold be same in such engagement, said members having portions thereof abutting against each other to prevent endwise movement of said members toward each other when said bolts are thus engaged.

at. In a fastener, the combination, with a pair of hollow bars arranged in spaced, aarallel relation, and a member to which said bars are connected at one end thereof; of a second member provided with a head having opposite undercut seatings, said head being adapted for reception in the space bet-ween said bars; fixed and movable bolts connecting said bars and extending across said space for engagement in said seatings; springs arranged in said bars and bearing against said movable bolt to hold the same 0 in such engagement; and cooperating means provided upon said members for holding them against relative endwise movement in one direction when said bolts are thus engaged. o. In a fastener, the combination, with a pair of hollow bars arranged in spaced, parallel relation, and a member to which said bars are connected at one end thereof; of a second member provided with a rigid, longitudinal projection having a head formed on its inner face, and provided with opposite, under-cut seatings, said projection and its head being adapted for reception in the space between said bars; fixed and movable bolts connecting said bars and extending across said space for engagement in said seatings; and springs arranged in said bars and bearing against said movable bolt to hold the same 1n such engagement, said projection having its free end abutting against the adjacent end of the first-named member to preventrelative movement of said members when said bolts are thus engaged.
